DAVID YOUNG, OF STOCKTON, CALIFORNIA.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 330,541, dated November 17, 1885.

Application filed December 29, 1884. Serial N o. 151, 422. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID YOUNG, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Harvesters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in that class of harvesters which cut, convey, thrash, clean, and sack the. grain in one continuous process; and it is designed to provide a means whereby the header may be elevated or depressed without in any manner affecting the upper attachments of the elevator-frame, and without affecting the tension of the conveyer.

In describing the device reference is had to the annexed drawings, in which Figure 1 is a plan view of the elevator and conveyer frames; Fig. 2, an enlarged transverse section through m m, Fig. 1; Fig. 3, a longitudinal section, and Fig. 4 an end view, of the elevator and timber of the feeder-box to which it is attached.

A designates the back beam of the conveyorframe, and B the front beam, carrying the sickle and guard-fingers. The floor E, as well as the beams Aand B, rest upon and are supported by the beams O O of the header. To the inner sides of the beams A and B are pivoted grooved rollers e, in which rest the framepieces G, which are slotted correspondingly to slots at in the ends of the said beams A and B, which are also slotted near the other end, as shown at a Aroller, a, has its trunnions resting in the slots in the ends of the pieces G and in the slots a, and a roller, a, has its trunnions extended through the lower ends of the plates G, on the sides of the elevatorframe D, the coinciding ends of the pieces G, and into the slots a The plates G, being secured to the sides of the elevator D, support the lower end thereof by means of the trunnions of theroller a, and the upper end is supported by a rod, H, extending through ears on the timber F of the feeder-box F, and through coinciding projections on the under side of the said elevator-frame D. A drum-roller, D, is journaled in the top of the elevator frame, and it is around this roller and the rollers a and a that the conveyer travels. The relative distance between these rollers remaining the same at all times, the tension of the conveyer must be constant. The header-frame is raised or lowered vertically, the distance between it and the feeder-box being therefore the same under all conditions. As the header is raised, the lower end of the elevator is likewise raised and its bearings advanced in the slots in the parts A and B. This operation will advance the pieces G on the rollers e.

When the header is lowered, the reverse of the above operation is true, thus in either condition relieving the upper attachments of the elevator from all strain.

I claim 1. The carrier-platform having the longitudinally moving carrier belt frame pieces, with carrier-belt rollers mounted in and moving with said pieces, in combination with an elevator pivoted at its upper end and connected at its lower end to the inner ends of said frame-pieces, substantially as and for the purpose specified.

2. The carrier-platform having the sliding carrier belt frame pieces seated on grooved rollers, in combination with the elevator pivoted at its upper end, and having stationary plates which are pivotally connected to the said frame-pieces, a roller-drum at the upper end of the elevator, a roller connecting the frame-pieces and the plates, and having elongated bearings, and a roller mounted in slots in one end of the said frame-pieces, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID YOUNG.
